Auxin-dependent cell cycle reactivation through transcriptional regulation of Arabidopsis E2Fa by lateral organ boundary proteins [PDF]
, 2011 Multicellular organisms depend on cell production, cell fate specification, and correct patterning to shape their adult body. In plants, auxin plays a prominent role in the timely coordination of these different cellular processes. A well-studied example

ACS Chemical Biology, 2007 Indole-3-acetic acid (IAA or auxin) is essential throughout the life cycle of a plant. It controls diverse cellular processes, including gene expression. The hormone is perceived by a ubiquitin protein ligase (E3) and triggers the rapid destruction of repressors, called Aux/IAA proteins.

Acta Societatis Botanicorum Poloniae, 2014 Results of experiments performed with 6-mm high stem sections of Pinus sylvestris L. confirmed the hypothesis that the fusiform cells of the cambial region respond to the arrival of indole-3-acetic-acid (IAA) at the signalling concentration in the ...

Cell Dynamics in WOX5-Overexpressing Root Tips: The Impact of Local Auxin Biosynthesis
Frontiers in Plant Science, 2020 Root stem cell niche functioning requires the formation and maintenance of the specific “auxin-rich domain” governed by directional auxin transport and local auxin production.

The transcription factors BEL1 and SPL are required for cytokinin and auxin signaling during ovule development in Arabidopsis [PDF]
, 2012 Hormones, such as auxin and cytokinin, are involved in the complex molecular network that regulates the coordinated development of plant organs. Genes controlling ovule patterning have been identified and studied in detail; however, the roles of auxin ...

A Photonastic Prototissue Capable of Photo‐Mechano‐Chemical Transduction
Advanced Materials, EarlyView.Mimicking energy transduction in prototissue assemblies remains a challenge of bottom‐up synthetic biology. In this work, prototissues integrating protocells with photothermal gold nanoparticle proto‐organelles and a thermoresponsive polymeric proto‐cortex are developed.

Auxin influx carriers control vascular patterning and xylem differentiation in Arabidopsis thaliana.
PLoS Genetics, 2015 Auxin is an essential hormone for plant growth and development. Auxin influx carriers AUX1/LAX transport auxin into the cell, while auxin efflux carriers PIN pump it out of the cell.

The AUXIN BINDING PROTEIN 1 is required for differential auxin responses mediating root growth.
PLoS ONE, 2009 BackgroundIn plants, the phytohormone auxin is a crucial regulator sustaining growth and development. At the cellular level, auxin is interpreted differentially in a tissue- and dose-dependent manner.
